Reye's Deli, a Mexican bodega on the southwest corner of 4th Ave and 14th St in Brooklyn, is a fairly normal corner bodega that has great prices on large quantities of cheap beer and a good selection of Mexican ingredients such as tamale wrappers, mole sauce, and assorted spices. They also have a strange assortment of random ephemera, such as a pair of absolutely enormous (3 feet long) hand- carved wooden spoons hanging from the ceiling ($7), and a box, hidden under the spice rack, of homemade sandals. According to a pencil scrawl on the box, they are only $5. I only recently discovered after months of buying crap there, they also make great tacos and sandwiches.
The place is usually open 24 hours a day, but occasionally it is closed, and occasionally when it is open they don't make food, so caveat emptor.
They have three types of taco, chicken, beef and pork. All are $2 a piece. They are very simple, but humongous. When I ordered a chicken taco, the cook pulled what appeared to be an entire breast out of the fridge, cook it, cut it up, and put it in my taco. Tacos consist of two flour tortillas, seasoned meat, frest cilantro, and salsa (tomatillo, I believe) on the side. I wouldn't consider myself any sort of authority on Mexican food, but I've eaten at some of the well-reputed Mexican taquerias in Sunset Park and Hell's Kitchen, and these definitely compare favorably.
Their sandwiches are on large italian heroes, stuffed with onions, peppers and meat. They are huge, delicious, and $6.
At 24 hrs a day, and in a more convenient neighborhood than Sunset Park for many gringo chowhounds, I consider this a great discovery. Far better deal than the taco bell down the block, which closes at 10 every night anyway. Can't wait for summer, when I'll buy a pair of those sandals.
