Siam Smile Thai Restaurant

You'll find yourself on a quiet stretch of Holyrood Street in Newport, away from the main drag but close enough that locals know exactly where to go when they want Thai that doesn't mess about. Siam Smile takes its food seriously—the kind of place where they're not trying to soften things for British palates, so if you order spicy, you get spicy. The room itself is modest and straightforward, decorated in that warm, no-fuss style that lets the food do the talking. Most nights you'll spot regulars at the tables, which tells you everything you need to know about consistency.
