OpenSeas Cafe
Top 18% Key Biscayne Restaurant · #7 of 55
The quick read
Among restaurants in Key Biscayne, this venue ranks well above the middle of its comparison group, and that reading comes from a full-size, city-specific sample with no shortcuts, so diners can trust the strong standing as solid, well-supported evidence rather than an early guess.
How we read the evidence: There is no prior ranking history for this business, so a ranking change over time cannot be shown. There is not enough ongoing tracking data to assess stability or trend for this business.

Methodology & refresh
Computed from public Google data · 725 reviews on Google · updates automatically. Additional public review sources join as their data comes online. Topic analysis is based on mention counts in review text, not star averages. The "rating distribution" layer reflects every review on the platform; the "lexicon analysis"/"AI analysis" layer is based on the sample of reviews actually analyzed. The average rating is measured against the Miami-Dade market average of 4.3 across 17,504 restaurants.
