Linda's is one of the places on the Rath-U-Thid street seafood stretch close to the Novotel. We tried several of them but it turned out that Linda has become our favorite. Linda is a friendly person who gives great recommendations and suggestions on methods of preparation for whatever seafood you chose.
She is also a business woman, so I highly recommend to check prices with some of the other places there and negotiate your price. I've never seen anyone being ripped of there but comparing prices may just give you a fantastic meal for a very low price.
Especially in the off season September or October there is a lot of room to move :)
Our dinner for 2 contained an unforgettable spider crab in chili, a BBQed Red Snapper, Squid with Basil, morning glory, rice, tom yum seafood soup and plenty of drinks. Total damage was less than 1500 baht...
