I came here awhile back on a whim when I was staying at the Venetian.
We didn't have reservations and we just waltzed in and got seated pretty quickly. The restaurant was one of those cool gastropubs which is a nice break from all the other fancy restaurants at Venetian. A really good casual restaurant for a quick lunch or casual dinner. When you walk in, the restaurant is dimly lit. I really liked the feel of the restaurant. Casual and nothing too fancy. A good place to hang out with friends and drink before a wild night out.
When we got the menu, the one thing that pleasantly surprised me was the how decently priced everything was. Especially for Vegas standard. AND the food was good! Whaaat??! But the one thing that really sold me was the vast amount of beer they served and they're only $7-8.
We ordered an array of food. From the bone marrow to the poutine, I enjoyed it all! Very good food. The BF ordered the pub burger which he really enjoyed. My favorite in the restaurant was definitely the mussels and clams. SOOO delicious! The broth had a good flavor that by the time I was finished with all the seafood I was dipping anything that I could find in it. Bread, fries, you name it, I tried it.
I would definitely come back here if I was staying at Venetian or Palazzo again. It's not a must try in Vegas, but it's definitely a good one to try if you're staying at either hotels.
