Crawfish Haus - Diamond Bar

Amazing!This place blows The Boiling Crab, Kickin' Crab, and Seafood Crawfish out of the water. It feels more authentic Vietnamese-Cajun than the other establishments, and we love that. They're very attentive to you and your table and I love that the brought out the waters immediately! They offer gloves and apron. The dining room is large and seating families is no problem. The food is high quality and the prices are competitive. This place was a little empty on a Saturday night, but the food was absolutely incredible. Wishing them more business!

We arrived at noon on Saturday and there was no other customers which was confusing because the food is very delicious! Service was friendly and quick.For appetizers, we got the Grilled Scallops $16) and it came in a sizzling plate! It was really delicious and great presentation. I ordered 1 lb Shrimp MP Nov'23 was $18) half pound sausage $7) side of rice and it was plenty of food. You can find the market price menu in the back by the cashier. The shrimp was 7.5/10 on the freshness but with the sauce it was 8.5/10.The House Sauce was sooo good.. it doesn't taste as cajun-y as Boiling Point but imo I like this more! The sauce tasted garlicky, limey, slightly sweet, and buttery. Beware of short reviews as this place offers 1 pound free crawfish for Yelp reviews. I would definitely return if I was ever in the area.

So delicious and flavor is ON POINT! Love the Viet fusion. Legit came back again the very next day for the crawfish and scallop. Their garlic bread also has actual garlic on it 10/10

Consistently great food. Been going here for many months and never had a bad meal. Grilled clams are awesome.

The food was beautiful in appearance and tastes great. The young waiter was very enthusiastic and welcoming. I hope more customers will know about such a good restaurant!
