Working on this as my own concept for a project, but here's what I envision:
Small rustic art nouveau district of sorts that mirrors PoE's mix 'n' match architecture style, but is meant to feel more like PoE's city area as opposed to just its 'Main Street'. Multiple small shops, one for blown glass and character-themed artisanal valuables, one for unique snacks and confectioneries curated by Confisco (so like his city branch), one for a wine cellar offering a large assortment alongside paired snacks and cheeses, and lastly a small alleyway that leads to a door to a 'hidden' Club 33 style bar on the second floor that is private except on certain days of the month (e.g. every other Friday night for TMs and a plus one, every Saturday/Sunday night for AP holders) and has exclusive mixed drinks with custom cups a la Grog Grotto. Manicured park in front featuring string lights and 6 food trucks parked throughout it each hosting popular foods from every continent.
And this would be part of PoE expansion that also adds an iconic flat ride and a quick service eatery to the waterfront overlooking the IOA lagoon.
