SLS had some deal with my room that gave us an app and 2 drinks for free with the room rate at any of the restaurants in the hotel, so we scoped them out and ended up at Umami Burger.
We chose the nachos - it just seemed like a simple choice. Definitely worth it. I would say that they are a smaller portion than what you would normally get - but delicious none the less.
Umami burger - yes. Just as described. Split one of these, the parmesan, onions, burger - combination melts in your mouth and I will be getting this again.
Beer selection - yes! they have a great beer selection and plenty of TVs to watch your games. Definitely a great sports bar option on the strip.
