This is the largest, and least pub-like, pub I have ever been to. It gets a D+ in the atmosphere department, but thats typical for the Monte Carlo.
The food is good but nothing to write home about. The portions are large, so you won't walk away hungry. The beer selection is decent but doesn't offer much in the way of uniqueness. In true Vegas style, the drinks are over priced so stick with the specials if you don't want a triple digit bar tab.
The service is friendly and reasonably fast.
The Pub is the best option for a decent meal at a reasonable price in the Monte Carlo.
