Hi all! Curious if anyone has done an event in Barcelona and has vendors they could recommend?!

Hi all - I'm in the beginning of planning an evening dinner VIP event near the Centre de Convencions Internacional de Barcelona (Barcelona, Spain) in mid-March for around 20-30 invited guests. Does anyone have any amazing recco's near this convention center in Barcelona? Or amazing activity experiences they would recommend in the area? I'd greatly appreciate any insight 🙏
