I had dinner at Seymour Burton recently and would like to share my experience, which was on the whole quite positive.
Popped in around 7:30 to meet a friend of mine. The restaurant, as you may have read, has one long communal table down the middle with other tables around the side, ranging from two-tops to a few larger tables that can take 6-8. The kitchen is more than open, it's right in the corner of the restaurant, wafting tasty kitchen odors throughout the room. The owner (?) peeled himself up from the communal table and politely asked if I had a reservation. Nope. They seated me at one of the two-tops to await my friend. (I should note that even though she was half an hour late, they gave me no attitude about the wait at any time. It probably helped that there were seats open throughout that half hour.)
The entire menu is written on a big blackboard on the right side of the room. Since I was seated on the right side, I had to get up and look at the blackboard, which was fine. I asked the waitress for a recommendation on red wine, and she promptly chose the two most expensive by the glass (and the only two above 9/glass.) I was unimpressed. I instead ordered a Bandol which was soft and fruity, a nice wine. (Revolution Bandol) My friend texted that she was delayed, so I ordered the mixed green salad (lovely - a heap of nice crisp greens with a gentle olive oil/lemon dressing for 6 dollars - exactly what I wanted.)
Good bread slices are served with a mild and tasty white bean puree.
My friend arrived and we went straight to the burgers, which, judging from my jaunt by the kitchen to go to the bathroom (and there are TWO bathrooms available - thank you! I hate it when a restaurant only has one, leaving you at the mercy of bathroom-lingerers!) were by far the most popular order. I asked if they came with anything but cheese and onion on them and was told "No." (I was also tempted by the fried oyster and bacon sandwich. Other nice choices included a trout with fries.) Unfortunately, the very tasty and not oversized burger came with a slick of mayo, which I abhor and which is why I always ask what is on burgers. Ick. Based on my kitchen-snooping, it's also on the oyster/bacon sandwich, as if more caloric goop is needed on such an item. The fries were tasty, on the thin and burnt side, and served in great abundance.
The desserts sounded great, particularly the house-made chocolate whiskey ice cream and the apple pie with caramel ice cream, but we were full after our meal and took our leave.
All in all, I enjoyed Seymour Burton. The room has a nice vibe and it would be a great place to catch up with friends or for a first/second date (or 30th date). They take reservations and I would suggest them for Fridays and Saturdays, though you could probably squeeze into the communal table if you are a party of two. If you do not like mayo, tell them NO MAYO ON ANYTHING!
