Unfortunately, Kinta and Kondessa will not be options for you - they don't open until 6pm each day - closed on Mondays.
I fear telling about this place, because surely of of you Scubaboard folks will start invading it
- but it really is too good not to share. It's the freshest local seafood I have found on the island and I just discovered it recently.
It's not a big restaurant - very small, but cheap and delicious! It's on Ave 20 at the corner of Calle 5 = it's on the SE corner of the block - not exactly on the corner - but you won't miss it if you're looking for it.
It's yellow and has sliding glass doors. It's simply says Pescaderia over the door. They have amazing ceviches and prepared fresh fish. 5 of us had a FEAST there for $700 pesos ($56usd) - we had a WHOLE cooked fish that was prepared in garlic and olive oil - prepared so that we did not have to worry about the bones - also 2 large ceviche platters, and some lionfish. My BF and I have eaten there several times and we love it.
If you want more of a restaurant, try La Perlita on Calle 10 between Av. 70 and 75 (taxi drivers will get you there), La Choza, or El Moro (open daily from 1:00pm until 10pm) except Thursdays - again, you'll need a taxi for this one!
I haven't had the pleasure of trying Paprika's yet, so I can't comment.
Have fun~
