Mart to Mart on Broadway in downtown San Diego's Gaslamp Quarter stocks standard and flavored tobacco, water pipes, hookah accessories, and glass pieces alongside a convenience market section. The product mix spans rolling papers, hookah charcoal, and shisha flavors in a format that overlaps with the deli-and-tobacco model at Hub Market Deli and Liquor on Fifth Avenue. The 431 Broadway storefront sits between Fourth and Fifth Avenues in the Horton Plaza district at the northern edge of the Gaslamp entertainment corridor. Glass inventory includes borosilicate water pipes, dab rigs, and replacement components such as downstems and quartz bangers. The hookah supply section carries the same shisha tobacco brands and coconut-shell charcoal products available at Tabac Plus on Market Street, creating a concentrated tobacco retail cluster within the 92101 core. Accessories include titanium and ceramic nails, silicone storage containers, and butane torches rated for precision-heat applications on concentrate rigs.
