What kind of gas stations do they have in your neighborhood?
Btw easy to find Belgian, trippel and quadruppels include unibroue, fin du monde and terrible. Safeway, Kroger etc will have those in large single bottles. I personally think they're highly drinkable, more accessible than bitters or IPAs and actually good value given the high alcohol content. I also think they're pretty sophisticated in terms of flavor profiles and good for beginners thinking about getting into fancy beers. The high alcohol content can be offputting to some, but they're fantastic for sipping.
My personal hope is that Belgians outpace the ridiculous faddy IPA explosion and stop exposing would be enthusiasts to cartoonishly one-note beers. Reminds me of the eighties garlic craze.
My favorite beer definitely not available in the OP's suggested locations is a series of beers called Hitachino Nest. Craft brewery outside of Tokyo that makes a Japanese imperial stout, white rice, red rice, wheat and other very clever Japanese takes on classics. Absolutely delicious and would be great for newbies in terms of flavor approachability and complexity. But eye wateringly at about six bucks per tiny bottle.
