Rather than eating an entire pizza from a single spot, I an thinking about getting a slice from various locations. I know most of the places on the Strip:
New York Pizzeria @ NYNY
800 Degrees @ Monte Carlo
550 @ Aria
Secret Third Floor No Name Mystery Meat @ Cosmo
DiFara @ Caesar's Food Court
Francesco's @ TI
Flour & Barley @ the Linq
Fulton Street Food Court @ Harrah's
Pin-Up @ PH
...and, of course, Pizza Rock across the street from Downtown Grand downtown.
Can anybody recommend some others? The only two rules are,
(a) It has to serve pizza by the slice, and
(b) It has to be within range of the Vegas buses, so anything south of Tropicana is pushing it.

I just got back from five nights in Vegas, and thought I'd mention a few things about where I ate. Note that the closest I came to breakfast was a boston cream doughnut from the Dunkin inside (IIRC) the Fremont. Also, anybody interested in "foodie" places does not have to bother reading any further.

I arrived at the Downtown Grand on Father's Day, and pretty much went straight to Pizza Rock across the street (literally - the DG casino entrance is across the walkway from the PR main entrance). Had the "Classic American" Pepperoni (about 13" - it's the only size this comes in); one of the better pizzas in the area, in my "old school" opinion; it ranks up there with Secret Pizza at the Cosmo. However, when I asked for a slice of "deep dish", the server at the time didn't know what I meant, and I ended up with a slice of Sicilian thick crust. (Then again, maybe I read the menu wrong - what I thought was Chicago style "deep dish" turns out to be "cracker thin crust".)

On Monday and Tuesday, I rented a car so I could hit the casinos I had missed the last few times I was here. Monday Lunch was at Original Tommy's on Boulder (just north of Longhorn and across Boulder Highway from Sam's Town); I decided to have a chili cheese dog, chili cheeseburger, and chili cheese fries. However, the chili was incredibly bland (you can order it with onions and/or jalapenos, but I chose neither), and it congeals rather quickly.

Monday dinner was at Via Brasil out near Red Rock. I was surprised how empty it was right after the USA-Ghana soccer match. It's typical rodizio, but I don't think it's as good as Fogo de Chao.

Tuesday lunch was 99 Cent Taco Tuesday at The Commissary; however, what they don't tell you is, these aren't the normal tacos in the menu - they're on small flour tortillas, and come only with steak or chicken, plus pico de gallo, lettuce, cheese, and I think guacamole. One of these days, I'll have to get out to Tacos El Gordo.

I finally managed to get out to Arizona Charlie's Boulder for the Tuesday BBQ Buffet Dinner. It was pretty much what I expected; a buffet with a few BBQ items thrown in, including having brisket and pork at the carving station. There was also pulled pork, but it was mixed with all sorts of things, so I passed on it.

After returning the car Wednesday morning, it was "back to the buses" for me. Wednesday, I went to Guy Fieri's at the Quad for lunch. I started with the Mac & Cheese Burger, which, although the menu doesn't seem to say this, includes three kinds of fries (shoestring, kinda sorta steak cut, and crosscut); the burger seemed to be too big for the bun and the meat patty tended to fall apart. I then went for the Cheesecake Challenge, and they weren't kidding; it was something like half of a 7 or 8-inch round cheesecake, covered in chocolate, with pretzels and potato chips (!) on it.

For dinner, I was still under the effects of that lunch, so I looked for something "small", and ended up at Toby Keith's I Love This Bar & Grill at Harrah's, where they had a 14-oz Ribeye special that night. A little undercooked for "medium," and a little fatty, but nothing to complain about.

Thursday, I just had a slice of pizza (Pizza Rock Sicilian) and a hot dog (American Coney Island over at The D - bland) for lunch, then dinner at the Aria buffet, mainly because (a) I got a free one from MyVegas, and (b) it claimed to have an Indian station, but it was pretty much just Tandoori chicken, one type of chicken curry, and some rice and naan. It did include some halfway decent desserts, like bananas Foster.

I just got back from five nights in Vegas on the "pretty much anywhere you can reach by bus" plan, and here's what I had:

Sunday dinner - I was staying at the Rio, so right after I checked in, I headed to Carnival World. I expected a little more variety, especially for the price, but the fact that I didn't go to the seafood or sushi stations may have some effect on my opinion here. However, why is it that everybody's idea of a BBQ station seems to be a pile of fatty beef ribs, a pile of stale cornbread, some chicken pieces, and occasionally a pile of "BBQ beans"?

Monday lunch at BurGR (at Planet Hollywood). The burger was excellent - it rivals BLT for the top of my list - and they do go overboard on the fries as well, but when I ordered a pudding milkshake, I was expecting some mixture of the two; instead, it was pretty much a half-glass of milkshake on the bottom and a half-glass of pudding on the top. Was I supposed to mix them myself or something?

I was planning on making my way out near Red Rock and having dinner at Via Brasil, but something in my stomach (and my legs) was disagreeing with me, so I headed back to Rio and went to All American Bar & Grille, where I ordered a dry aged New York Strip (which, they don't bother to tell you in advance, is bone-in - it appears to be the non-filet half of a porterhouse) and a side of macaroni & cheese. I was expecting the M&C size to be something that would fit on the plate with the steak, and was surprised to see it served in a (shallow) soup bowl; I didn't quite finish, especially as the "medium well" steak I ordered was still red near the bone. I expected a little better for a $30 steak that was still only USDA Choice.

Tuesday lunch was at Smashburger on the east side of UNLV (I was in the area to go to the Pinball Hall of Fame about two blocks east). Nothing remarkable, although the burgers I had for lunch this trip did tend to lie in my stomach for a while - something that happened to me last year with a Fatburger as well.

I had a comp for the buffet (Cravings) at the Mirage, so I tried it out for dinner. Nothing out of the ordinary, except that I didn't remember there being very many desserts.

Wednesday lunch was at Burger King - that was pretty much the only place in the area at lunchtime between lengthy bus trips.

Wednesday dinner was at the Ports o' Call buffet at Gold Coast, and it's worth it if you want to turn it into an all-you-can-eat for something in particular (e.g. pizza, or turkey breast), but despite the fact that it had prime rib, it wasn't really worth the effort.

I was downtown on Thursday, so for lunch I had a "four cheese" burger at the 777 at Main Street Station; it appears to be a burger where they melt four kinds of shredded cheese on it - not impressed.

Finally, one of the best "quick eats" I had in Vegas was from an unexpected spot - the meatball sub at the deli next to the Sports Book at the Rio. (Maybe next time I'll try out the half-pound hot dog as well.)

BTW...no, I never did get to the "BBQ Buffet" at Arizona Charlie's Boulder (that BBQ station at the Rio buffet turned me off), and I didn't get to a rodizio either, although I did go to one in Columbus, Ohio the week before, so I wasn't particularly interested this time.
