My wife and I came here for a late lunch while were staying at the MGM's Signature hotel. At first we wanted to sit at the bar but most of the seats were taken and the all of the two person high-top tables had "reserved" signs on them which I didn't understand. We grabbed a beer and a cider (quite expensive at nearly $20) and asked for a sit-down table.
We ordered the 1842 (caramelized onions, mushrooms and truffle aioli) and the Bacon burger, both at $19.00 each. I thought they were good. I also ordered the "hair of the dog" which was a shot of Jim Beam and a shot of pickle juice. We call this the "pickle-back" here in San Diego. At only $8 this was possible one of the better values. The interior is not terribly huge or decorated in a memorable way. There's a little outside patio type of area with standing hooks for your jackets or hats which I thought was a nice touch.
Overall I wish there was more variety on the menu and wasn't blown-away like I am at some other Vegas restaurants (hence only 3 stars) but I would go back to Pub 1842 try some other things which may get it more stars (especially these lobster corn dogs I keep hearing about). This is my first Michael Mina restaurant.
