baskin Robbins is an international chain so Busan has three of these. I went to the one on '1496 U-dong Haeundae-gu'. very tasty treat. I guess I got carried away with my selection :-)
This is the best meal I ever had. Jagalchi is an absolute 'must-see/EAT' place in Busan. Simply pick a fish / crab / bizarre sea creature, give it to the assistant, go upstairs and order beer and soju - your food is cooked and prepared beautifully.
