Two suggestions: Hudson Malone and Rye Ridge deli.

Bartaco is great for good Mexican and casual lunch. On the water too.

That's like asking for the best seafood restaurant in Maine. Pick a budget and it will almost certainly be great. Westport isn't my favorite town in the state by any means, but I've been into a ton of restaurants walking around and have yet to leave disappointed.

If you’re looking for a brunch vibe, Kneads. Expensive (duh, Westport), but I was very happy with my meal.

Overall I'd go with Kneads.

Question is too generic though - what type of lunch are you looking for? Personally prefer Don Memo to Bartaco, but they are very different types of places (and Don Memo is only open for lunch Fri-Sun). Layla's Falafel or Gaetano's Deli are good for take out. Romanacci is my favorite pizza in town, but plenty of good pizza and Italian food around. I never found any of the Asian spots in Westport to be great, but Kawa Ni and Rainbow Thai are solid. Organika if you need vegan. Granola Bar or Terrain are good if you need instagram girl vibes. Haven't been to La Plage so can't comment on the food, but can't imagine it doesn't have the best views.

Little Barn is pretty decent.

Terrain has pretty awesome food. Sometimes hard to get a seat so reserve one if you go on the weekend.

And great for kids if you happen to have those.

Rye Ridge? I’m surprised. Our office is walking distance and we don’t go because it’s slow and low quality…

Lots of good lunch spots. Match Burger in Saugatuck is great and consistently has the best burger in town. Hudson Malone and Spotted Horse are great if you’re in the downtown area!

Kneads, Match, Allium, Terrain, Gaetano’s, Walrus Alley.

That place that has food.

I’ve been disappointed by Hudson Malone 3 times and overpriced even for Westport. I like the vibe inside but didn’t love the food.

I like them!

It's for a gift, he just started working in the area. Life's pizza, sandwiches and salads and doesn't seem too adventurous

Terrain is nice. Maybe Walrus Alley. Lobster Burger.

That's sweet of you! I'd probably go with Layla's then. Good prices and not too heavy or adventurous for lunch. Maybe Kneads if they work on the west side. It's just more expensive, so a gift probably isn't going to go as far there. If your friend is working in northern Westport or Weston, Dilly Duck in Norwalk could be an option too (although it seems like they have egift cards turned off on their toast shop).

Work lunch always makes me think of Panera style food (like pre 2017 before it was bought and became terrible) - which Aux Delices is probably the closest to that, but it's not groundbreaking.

Layla's Falafel
