A very well-stocked sake shop, plus a small stand-up bar where you can try samples in small 50ml tasting sizes. Usually there are around ten sakes open for tasting, priced Y200-400. There's also a small snack menu - prosciutto, cheese, dried mentaiko. The retail side of the shop stocks over 100 premium brands of sake, and unlike many shops that seem to specialize in those humongous isshobin bottles that won't fit in your fridge, most of the sake here is in convenient 720ml bottles or in tiny single-serving mini-bottles.

Meishu Center (Hamamatsucho - Liquor shop). 5405-4441
A down-to-earth little shop that offers an impressive variety of sakes for tasting. There are two brightly lit, stand-up counters where a mostly neighborhood crowd gathers for an after-work drink - this is as unpretentious as it gets.
To say that this retail liquor specializes in shochu is an understatement: they stock 2300 varieties of the potent Kyushu spirits, and are ready to offer expert advice and tastings.
