O ya is hands-down my favorite restaurant in all of Boston. With steep prices and mostly two to three pieces per order (ranging from $8-38, with an exception of the $189.99 eight-ounce wagyu beef striploin), it is definitely a place for celebrations. T & I first headed to o ya for our 4-year anniversary, then I took my college roommate, Amanda, here when she visited from California, and this recent trip was to celebrate my birthday. Located in the small Leather District of Boston (yes, it exists), Tim and Nancy Cushman have been dazzling diners since 2007 in their loft-like open space that seats 17 at the bar, and only 20 at tables. Reservations for these highly-coveted seats can be made online for the bar, but seats at the tables must be called ahead (and be sure to 3 months in advance of the date you wish to dine). To make o ya even more accomplished, this year Tim Cushman received the James Beard best chef of the Northeast award and once again o ya landed on Boston Magazine's 50 Best Restaurants list (unsurprising really after you have had the honor of tasting their innovative combinations).
With a small sign hanging a block or so from South Station, and a large unmarked wooden door, at first you may think you have mistaken the directions...but you are correct, and behind this large door is a magical restaurant where you will have a magical evening.
With many menu options to choose from (including an omakase chef's tasting and a grand tasting menu), you have the option to either mark up the menu and let them be brought out as prepared, or order like a tapas menu, a few orders at a time while you enjoy and decide your next steps. We marked our menus up and handed them over, trying some new items as well as some of our favorites (you can find the menus here). If you are unsure, the waiters and waitresses are very knowledgeable, helpful, and friendly!
