Overview
Omg Seafood at 205 Moore St, San Marcos, TX 78666, United States, is the kind of casual seafood spot that keeps things simple, flavorful, and seriously satisfying. This is not a fancy white-tablecloth restaurant, and that is part of its charm. The setting is clean, comfortable, and straightforward, with limited seating, so it feels more like a place where the food does all the talking. The menu has earned attention for bold seafood flavors, generous portions, and fried favorites that come out hot, crunchy, and packed with seasoning. One of the standout choices is the fried catfish, known for thick, well-prepared fillets that taste fresh instead of muddy or overly fishy. The coating brings that golden crunch people look for in Southern-style seafood, while the fish stays tender inside. The fried shrimp is another favorite, offering a quality bite that feels worth coming back for, especially for anyone who enjoys seafood that is crisp, hearty, and full of flavor. Omg Seafood also has the kind of dishes that can sell out quickly, with gumbo being one of the items guests look forward to trying when it is available. Portions are satisfying, making it a good stop for a filling lunch or a relaxed dinner with friends. Another nice detail is that the restaurant is BYOB, which adds to the laid-back, local feel and makes it easy to enjoy a casual meal at your own pace. Service is often described as friendly and welcoming, helping the small space feel even more comfortable. For seafood lovers in San Marcos, Omg Seafood brings together big flavor, fresh-tasting fried fish, quality shrimp, and a no-frills atmosphere where a table, a chair, and a plate of well-cooked seafood are more than enough.

Lovely staff! We sat outside because the place was packed and got our food pretty quickly! The owner also very swiftly corrected a small error on my friends order and check in on us later. 10/10 planning an outing so I can go again :)

I just love this place. I crave their fried catfish and shrimp. It is so flavorful. The filets are nice and thick. I have never gotten a filet that has the fishy, muddy tasting bloodline. Every time it is just perfectly great tasting crunchy fried fish. So awesome! It really is OMG seafood! The shrimp is a very good high quality shrimp. Customer service is awesome, too. The inside is nothing fancy, but it is clean, and when the food is that good, all you need is a table and a chair to enjoy it! Will be back tomorrow with a friend!!!

Went there today for the first time. Ordered everything to go. The crawfish was absolutely delicious and very spicy. The shrimp was perfectly done and very tasty. The catfish was very good but there was only one fillet on the platter which was very disappointing. Sausage was “ok”. Potatoes and corn were also excellent. Not a lot of seating inside. It was kinda hot inside and the air was still with no fans so I wouldn’t have wanted to eat inside anyway. Plenty of seating outside though. And BTW, we were told you are welcome to BYOB beer and alcohol.

Scrimp was excellent. Gumbo was OK...liquid was from crab boil bag and too much sausage but otherwise ok for Texas (it is not traditional south Louisiana gumbo per say). Worth the drive to eat here. In a tough part of town but I felt safe. Don't expect a nice restaurant as it is a dive both inside & out....if that bothers you, take out. Cooked fresh and hot.

My daughter loves crawfish or how you say it ( Mudbugs ) from OMG. I have two daughters that were born in Louisiana. So they grew up eating crawfish. Not me!! Sorry to say. Lol!! But I do love eating the corn, sausage and mushrooms that they put in the crawfish boil. OMG really do have the best Cajun seafood in town

I truly enjoy coming to OMG Seafood, so much that I've been coming once a week so far. For the passed three weeks. Tonight my boyfriend and I got # 1 Boiled Crawl fish and I got the #8 Shrimp Combo. The customer service is very pleasant. I was greeted from the moment I walked in and was told to have a great night when I walked out. I truly will be recommending this restaurant to my family and friends when they come to San Marcos Texas.

Great crawfish! Great fish! My wife loves crawfish, I'm happy to stick with fish, crab, and shrimp lol. OMG staff are always friendly & helpful; the restaurant is always clean. The food is tasty. I only wish they did boiled shrimp along with the fried. We highly recommend them and will continue to come!
