ALL Parties of 10 or more must coordinate their reservation by emailing Juan Thomas at JThomas@harborsidehotel.net A Few Things to Know: We allow a 15-minute grace period for all reservations. After this time, tables may be released to waiting guests. While we always do our best to honor seating requests, please note that specific tables cannot be guaranteed. We kindly request 24 hour notice for cancellations. For the best possible service, parties of 15 or more will enjoy a coursed meal service. À la carte dining is not available for groups of this size, as the coursed experience ensures smooth service and timely delivery for all guests at the table. We look forward to hosting you at Portum where every meal is crafted with care, every cocktail is poured with style, and every visit is a vibe you will not forget.
