Gastown is among the world’s most unromantic names for a neighborhood. But this oldest quarter of Vancouver is among the city’s most charming, with pretty brick warehouses now occupied by shops and restaurants. The neighborhood, at least for now, has a concentration of upscale galleries focusing on top-quality First Nations art. But more than one gallery owner complained to me of skyrocketing rents, and some of them plan to relocate in the near future.
