We visited Tookta's in March on a trip to Brighton. We were encouraged by the trip advisor reviews and, had a really good meal there. The menu is limited but, they do a few dishes awesomely well.
The good points:
Best Thai green curry I have EVER eaten. You won't be disappointed.
The not so good points:
The restaurant is very tiny so get there early if you want a table.
They normally don't take bookings unless you are a large group.
I think Tookta's may be a victim of their own success, the food is gorgeous but the staff seemed really rushed off their feet when we were there and were preparing for a very busy night. I would go back but, perhaps not at a weekend as I think I may have enjoyed it more if it were quieter.
