Talked to 3 different employees there. None of them knew about gluten or could help us with ordering GF. We left. Becareful.
Fresh seafood with a lot of options (steamed or grilled or raw, for the non GF people in your group there's also lots of fried options)! I had a half dozen oysters and 2lbs of steamed mussels, they also have a few ciders and wine to drink in addition to sodas etc. My friend had shrimp in garlic butter/old bay and a steamed crab, and my husband had a lobster roll (obv that's not going to be GF). We'd come back in a heartbeat next time we're in the area!
I love Redondo Beach, and Quality Seafood is always a highlight of our trips. They have a huge selection of seafood, some of which can be eaten on sight. I always go for the clam and oyster bar, which are naturally gluten free. Yesterday, I had a great conversation with one of the employees who gave delicious recommendations. The selection can be overwhelming, so it's essential that the staff here is great.
