We ended up here for lunch out of desperation on 12/22. We had a party of 12 and were heading to the Las Vegas Discovery Center (for kids) and was looking for a buffet. Golden Nugget was closed as well as the one at Fremont. So we walked all the way to Main St. Buffet is pretty damn cheap at $9 per adult. Kids are $1 less. IF you sign up for their rewards program, you get $1 off. There was actually a line for this place. I would say that it is a tad of an upgrade from Hometown Buffet. service wasn't too bad. The place is big and they have decent variety.
Some of the standouts...
Fried chicken was surprising good
Tri-tip/Brisket was ok if you covered it with Creamy horseradish
Decent dessert selection
Miso Soup was good
The Bad...
No Mac N' Cheese
They had cocktail sauce but no shrimp to go with it
Not too much for vegetarians.
You basically get what you pay for. I wouldn't go back.
