I work/live about 10 minutes away and some weeks am at Celsius 3-4 times. I love this place.
Simply put, the food/experience here is always fun and great.
When you first come into the bar, you notice the black floor and the nice sized aquarium on the right. Then you're quickly greeted by "the hot hostess of the day" and shown a table. I normally get a seat in the back because I like to see the TV screen that displays a closed circuit video feed of what the sushi chef is preparing behind the counter. Nifty.
The ambiance is pretty damn hip. Hip like, you can't help but feel cool sitting there because the bar has a big wall of alcohol, there's a nice aquarium sitting tall enough to admire from across the room (and out of reach of chopstick wielding children), the black floor gives the place a club-like feel and the music is chosen by the employees which helps convey the overall "with it" vibe of the entire bar.
The food itself is great too. Although I'm allergic to shellfish I can always find something good to eat here. Off the top of my head, I'd recommend the following:
* the bomb
* vegetable tempura with a side of rice
* the seaweed salad (it always tastes crisp and fresh)
* the Valentine roll
* the Frankenjin roll
One of the best things about this place is it's OPEN LATE!! These guys are hardcore and don't shut down until midnight so if Delux is too far away and you want something other than In & Out - swing by Celsius. And ladies, if you're single - all the chefs are too. haha!
