Adjaran khachapuri — the boat-shaped bread filled with melted sulguni cheese and topped with an egg and a knob of butter — is the dish Batumi gave to the rest of Georgia, and the city is studded with places that do it well. Khachapuri Sakhli ("the khachapuri house") on Gorgiladze Street is a reliable, no-fuss spot to try one if you only have time for one meal.
You sit, you order an Adjaruli of the size that seems sensible (the standard is enormous), and a wood-fired version arrives in a few minutes — golden, eggy, salty, and rich. They also do other Georgian classics — khinkali, lobiani, ostri — but the Adjaruli is the reason to come.
