We asked about this place at our poker table. A local told us "everyone should experience Battista's.". It's a family run Italian restaurant located between Flamingo and Bally's. It is not in a casino, but is located by a mini-mart. Reservations are recommended and it is only open for dinner (4:00 - 10:00). All meals include garlic bread, soup or salad, all the wine you can drink (house wine red or white only) and a cappuccino. We had the lasagna and chicken parmesan, which came with a side of pasta. Complete meals range from $20 to $40. A little old Italian guy goes from table to table and plays his accordion for tips.
The food was OK, nothing great. The wine was not good, but it was free. The garlic bread was great and the cappuccino was excellent (and I don't like coffee).
