I went to LA Boil with my friends on a Sunday night during when they had the 50% off a lb of shrimp OR mussel per person. Of course only one order and the rest of the orders are regular price.
Nonetheless, my friends and I in total had 2 lbs of shrimp, 2 lbs of middle, 1 lb of clams, 2 orders of Cajun fries (delicious) and then corn on the cobs about 4-5 orders.
To start, they had these cute bibs that you can draw on for yourself to be creative. served in big plastic bags - they also offer you gloves as this is a very hands-on experience!
LA Boil sauce was a mix of everything together - from Cajun to some of the other sauces, highly recommend that as a general point. I would say to get 'medium' spicy level cause the "spicier" you go, the more the sauce taste.
Overall, the bill came out to be about 18 before tip per person which I thought was awesome with the event. Would definitely come back.
