While exploring around Sagrada Familia we discoverd this place on a sunday and it was full. OYISI = japanese and means TASTESGOOD /DELICUS even a real japaneese spell it: OISHII Well on our last day it was time to taste delicus food ;) It has open from 12AM. and while we arrive NO people where there. We did not want to be the first! So we waited almost another hour and entred — TOBETHEFIRSTANDONLYGUEST anyway. on a tirsday. The buffet looked okay, with fried rice, small spring roll and some other chinese food. Some sushi(only rice/samon) and sashimi(raw fish). Beside they had some vegetables and cattlefish + meat with could be fried on request. Even they said its a japaneese restaurant its more a chineese. They did not speak japanese and very little english! So I belive spanish speaking locals we have better luck(I hope some locales can give another review). The place was clean and light. The price for the buffet was 8 euro but all drinks had to be orders exclusice.
