You may not have been aware that on Sundays Brother Jimmy's on 92nd & 3rd offers all-you-can-eat BBQ with unlimited refills of beer or soda for about $23 ($4 more than a regular order of a half rack of ribs with 2 sides). I have had some decent ribs here from time to time, so the AYCE deal would sound like a pretty attractive bargain, assuming the rowdy frathouse/sportsbar atmosphere does not phase you. But there is a catch.
First: If your plan is to focus on the meat, be aware that you will also have to order two sides - yes, those carb or veg loads that will help fill up your stomach. Second, on the occasions I've been to the restaurant, there is a ridiculously long delay between the time that an order of meat goes in and a plate arrives back at your table. I don't know whether they are growing the grains to feed the livestock out back or what, but it shouldn't take more than 25 minutes to get your food, especially if it's an AYCE meal. But it does, which means that after a first round, you will probably have lost your appetite by the time your second plate arrives.
If you can handle these caveats, or if you just want to hang out with the guys (or girls) watching the game on the tv in the back and drinking lots of beer, it may be worth it. Otherwise, I'm not so sure.
I've also noticed that the food here can be inconsistent. I've had some very good ribs here at times. On the other hand, I've also had meals in which the first round of ribs was delicious but the second tasted like it wasn't even cooked in the same kitchen, let alone by the same person.
