C'est What is a great beer-bar, a place for beer snobs, beer lovers, and beer drinkers to rejoice in their collective passion for hoppy (or malty, or whatever) suds! This place is everything the Rhino is not: excellent service, clean taps, clean space, comfortable seating, tasty food...
Sure, it's located in what essentially amounts to a basement, but I never really felt like i was chillin' in someone's dank and dirty. The place is spacious, well laid out, and lit just shy of atmospherically (not sure what that means exactly, but I hope you catch my drift).
The beer list is not insane, but I appreciate that -- there's not a bad choice to be found, and the seasonals and cask offerings are yum, every one. I was particularly fond of their house chocolate stout!
But while C'est What will never stray from its beery roots, it's the food that really struck me. As pub food goes, they have some great options: I highly recommend the house-made veggie burger w/ yam fries, made with ancient grains, chick pea, and more. Awesome. One of the best veggie burgs I've ever had, pub or no pub, though it bears mentioning that the patty is deep-fried. So much for the healthy option! As for those yam fries, man, delicious, even if they do range from crispy to floppy depending on the chip. Texture didn't matter much, they tasted that good.
Finally of note, C'est What doesn't, as a general rule, offer tastings of their beer... but they will, if you ask nicely. And "a taste" amounts to probably 5oz, so I understand why they're reluctant. So again, ask nicely, thank kindly, and tip well, and they'll be more than happy to give you a few nips of what's on tap to help educate your decisions. Plenty of time for beer-blind choices later!
