I went to Monti's with a group of people very diverse in age. Since I was there plenty early I got a chance to visit both the bar and the dining area. The place has some great history and it was neat to read some of the memorabilia on the walls. My favorite was the cow picture...you'll have to go there to read it.
The bar area is great. It's separate from the main dining area and has a good casual feel to it. My bartender provided good service. They have a limited number of beers, but their selection is diverse and will probably suit most people, plus, it was happy hour...woohoo!
Here's a summary of the dining experience:
Food: Very good. My steak was good size and sides delicious. They have nightly specials and I ordered the fillet which came with 2 sides ($12.99). Very reasonable.
Promptness: Very good, was a busy night but our meals arrived in about 15 minutes
Service: Our waiter was noticeably proactive with water refills and had good recommendations (didn't upsell like another review mentioned).
Recommendation: If you're in Tempe looking for a good steak house, I strongly recommend Monti's. You won't pay $80/oz like other steak houses, but if you have money to burn then please contact me.
