Wagyu flat iron steak was delicious. I was surprised at how flavorful and tender the cut was. Lobster tail was incredibly tender and not too fishy. Also had the loaded potato that was soo big I couldn't finish it. And I always finish my meals. Top notch service and great ambiance on the back deck.

Excellent steakhouse. Every once in a while, I'll venture to a steakhouse. Most of the time I am underwhelmed but not here. The 9oz Filet was cooked to perfection. The French onion soup and Caesar salad were both very good. The side of asparagus was also cooked perfectly - a little crunch but still cooked.

Our first night on the Vineyard we had dinner here. Everyone including the owner were very friendly and accommodating. Our bartenders were fun and friendly. They have lots to choose from on the menu. If you leave hungry it’s your fault.

While vacationing at Martha's Vineyard with my sister, we dined at 19 Prime. The service was excellent. Our waiter, Ion, provided outstanding service. He was knowledgeable, kind, and amusing. His meal recommendations were excellent. He made our visit to 19 Prime a beautiful experience. Now let's talk about the food! Superb, Outstanding, Simply Delicious. The best meal we had while visiting the island. Thank you 19 Prime for an amazing experience.

What an insanely fantastic gem on the Vineyard! This was hands one of our best meals ever had…like ever! From the local oysters to the cauliflower carbonara and the fantastic scallop crudo; there was nothing on the menu that was not impressive. On top of the memorable food, the service went further than expected and was impeccable. Cherry, our fantastic server set the stage for the wonderful birthday meal we were there to have. Thank you so much 19 Oysters/Prime Steakhouse for this memorable meal! We’ll be back soon, no doubt!

Tough to get in but trick is to go an hour or two before you plan on eating, putting your name on the list and they’ll text you when your table is ready. We stopped at another spot for drinks until they texted us. Food was really good. Octopus was by far the best thing we’ve eaten in MV. I read that most restaurants are awful on the Vinyard but this place is phenomenal.
