Had dinner last night at Bistro Cassis, which opened this week on Columbus at 70th St. The place was buzzing and there was a 20 min. wait for a table (they do not take reservations). The bar/waiting area could have been more comfortable, but their estimate on the wait was right on so we didn't mind. It's an adorable bistro where the decor, food and many of the waitstaff are French. I was impressed with how smooth the service was given they'd only been open 2 nights. The bread was served crispy and warm with butter and, to our great surprise and delight, pate! Both my friends ordered the steak frites with maitre'd butter, which they loved, and I had the onglet bordelaise. The meat was tender and the sauce was deliciously rich and flavorful. I asked to substitute the mashed potatoes that accompanied it for french fries and the waiter brought a side of frites in an adorable silver cup with parchment paper at no additional charge. The waiter told us the wines by the glass in lieu of giving us a wine list, which was a bit worrisome to me, but the wines we took a leap of faith on and ordered after he described them as "a fully bodied red" and "a merlot" ended up being quite nice. The profiteroles for dessert, which we shared, were a bit of a disappointment (they looked much better than they tasted...) but on the whole, this is a great place. Prices are affordable (teens to mid twenties for entrees) and they have specials each night of the week including french favorites like coq au vin, boeuf bourguignon, etc. The brunch menu also looks great. Can't wait to make it back as it's likely to become my new favorite place in the neighborhood! If you're looking for a place on the UWS, I'd definitely give it a try.
