No one stops him! People will just continue staring as he passes. Some people, most of which are those who weren't on carriages, will discreetly follow. Or not so discreetly. But people will continue to remain far away from him and not approach, merely Stare.
The gate opens up to townhouses on both rows, and some sort of square or plaza in the middle, which appears to currently be hosting a farmer's market of people selling fruits and vegetables and other food products. It's too far away to make out what the specific products are, though, unless he moves closer.
In front, and over to the side, there's the smell of Tasty Food, and tables arrayed on the sidewalk, beside what looks like a business. There are people gathered on tables, eating in the open using their tentacles. They are shaded with umbrellas above the tables. The people are talking to each other while eating. He won't be able to tell what exactly they're eating unless he moves closer.
There are also other businesses, whose signs he can read. Of the ones nearby: one advertises 'legal services', another sells stationery, paper, and calligraphy supplies, another sells books and articles, as well as teletype machines, and the last one sells phonograph machines and vinyl records of music.
The aesthetic of the businesses and buildings is Very Clearly Coordinated, in what Earth people would say is similar to Art Nouveau. Lots of stained glass, curlicues and latticework in wrought iron, gentle greens, tans, and whites, and floral motifs. Even the signages and logos for the businesses, as well as their advertisements, obey said aesthetic, even though they are clearly marked as Being Separate Businesses Which Are Not The Same. They do vary in how many accoutrements they put: some go all out, while others are more reserved, but never in a way which appears clashing or jarring.
It is also noticeable that, while the remna are not wholly coordinated in aesthetics the same way the buildings are, clothes which have a similar look to the buildings are more common than any other look, at least, from the people Vivai has seen so far.
