Owner Piano, who named her restaurant for her mum Mon, has spiced up Vienna's burgeoning Southeast-Asian food scene with a menu of southern Thai flavours, street-style decor and an indie soundtrack. On mild nights, a young, happy crowd spills out into the courtyard, while single diners pull up a stool at the large communal table or window seats within.
Piano's plump tod mun (fish cakes; €6.50) are some of the best outside of – or in – Thailand, and her herb-strewn papaya salad (€7.50), full-frontal pork larb (€8) and the addictive sticky-rice accompaniment have a cult-like following. There's an interesting list of other snacky starters, curries and stir-fries but it's hard to go past the daily curry and rice (€7.50 to €8.50), which often uses fresh, seasonal ingredients while still keeping it totally authentic (note that it's always fish on Fridays, but it often sells out by lunch).
