In my three day trip to Vegas, I ate one slice of pizza and the fried chicken Benedict from Hash house A Go Go. This was plenty of food.
I've been to the Hash House A Go Go in San Diego (original, I think) and this place compares nicely. Huge portions and interesting combinations of things.
I really enjoyed the bloody Mary, and I don't usually like Bloody Mary's.
What I did not like about this place was tha there was zero reception in the waiting area, and they won't seat you until your whole party is there. No reception, no seating till all is present, 20 minutes waits and Vegas are a bad combination with larger groups.
Overall, its a nice mid-range priced place to eat. If you are not a big eater then the $2.50 split plate cost should be more than enough food.
