About J.Boroski

Down an unlit Thong Lo alley behind an unmarked door, this moodily lit retreat trades menus for intuition. You name a base spirit, a flavor craving, or a concept—smoky mezcal, bitter twists, or crisp fruit notes—and bartenders build custom cocktails on the spot. Low music keeps conversation effortless while the team shakes drinks to taste, pouring everything from peach-tinged rum Old Fashioneds to balanced gin Negronis.

  • Menuless Bespoke Cocktails: Bartenders craft custom drinks on the fly to match your preferred spirits and flavor profiles rather than pouring from a printed list.
  • Hidden Speakeasy Setting: Tucked away down an unlit alley without signage, offering an intimate, low-volume setting suited for quiet conversation.

Why Guests Choose J.Boroski

Tailored cocktail artistry behind an unmarked Thonglor door

  • Bespoke Cocktails Without a Fixed Menu

    Rather than relying on a printed drinks list, bartenders consult with guests to craft bespoke cocktails matching preferred spirits, flavor profiles, and sweetness levels.

    There’s no physical menu here; instead, the staff ask about your preferences and craft drinks tailored to your taste.

Beyond the menu

  • Recipe Fine-Tuning and Adjustment

    Bartenders actively invite feedback and will rework or adjust a bespoke creation until it exactly satisfies your palate.

Before you head over

Practical advice for navigating the bespoke menu and hidden entrance at J.Boroski

  • Clarify Spirits and Budget Upfront

    The bar has no printed drink menu or fixed price list; drinks are built custom per order and billed by the specific spirits and pours chosen, so be clear about your preferred base spirit and budget upfront.

  • Watch Closely for the Unmarked Entrance

    The bar is concealed down an alley without any exterior signage or storefront markers, so keep a close lookout for the secluded alleyway when approaching.

  • Arrive Early or Reserve for Bar Seating

    Seating along the illuminated main bar is limited and sought-after for watching bartenders mix drinks, so arrive early or reserve ahead.
