If you're staying at the MGM, the Avenue Cafe is a good option if you don't want to gorge on the buffet. The restaurant can easily accommodate large parties and didn't have a problem seating us when only 7 of our initial party of 10 was there when we arrived. The service was especially friendly with lots of trips back to refill coffee and waters, and our server played along with our off-kilter jokes. I had the chilaquiles - a huge amount of tortilla chips with red sauce, sour cream, queso, and two eggs. Super tasty and filling. Even being super hungry, I wasn't able to finish them off. Everyone else was pretty pleased with their dishes as well.
