Here's a pic from Lek's. 160 Baht - double what you pay in KKP

Can I get a second go please?   This time I'll contain my 3 answers to just one very pleasant street along a canal in the old town and next to Romani Nat Park so this makes for a good day out with some of the best street food in the city too. HiSo Curry Rice PaEw does good curries, particularly the crab curry and stir-fry with chilli at bargain prices despite selling good seafood and other expensive ingredients. They're very popular, I go there prepared to fight for my crab curry when it's just been cooked and then sometimes do it again afterwards as it's addictive stuff despite the other tempting food a few steps away. https://maps.app.goo.gl/HMvDdxWrvQ5bd1At6 Jack's Chicken Rice serves some great chicken rice, they're lovely people too. It may be simple but it's good. I often go here after running in the park nearby and skip the additional fried chicken if trying to be good but that's difficult. https://maps.app.goo.gl/Wft2NM4HYBX2NEmd6 Aunty Pien's noodle shop might be the best place of all the excellent options on this little strip. It's been there a long time and I love the ladies who run it, unfortunately they have refused to adopt me so far so I only get to eat their amazing noodles when they're open. Go here even if you're not in the area, get the chicken noodles, I have the additional squid and skip the red pork but the Mrs says I'm doing it all wrong. Anyway it's all excellent, she's a fantastic cook and you can smell the magic coming from her wok so people like me can be found standing around making a nuisance of ourselves while she cooks our food. I will be going there soon, guaranteed. https://maps.app.goo.gl/1oEUX57UaZXZ4wqa6   Honourable mention goes to the lovely Rad Na noodles a few more steps down the road and the moo ping stall at the start of the street  where the Mrs has been known to fill up before we even get to our planned destination.   If you're interested in going to these places they're very close to Sam Yot MRT so are simple to get to from Asoke.

Just fyi for those in town now or soon, Thai Niyom is currently being renovated. They closed on 10/7 and say they will reopen "in November." I was totally bummed when I got here, called to make a reservation, and learned that I''d arrived a few days too late.

Rang Mahal is in a totally different class than Bawarchi, I promise.

Seconded. Peppina is genuinely good and might even stand up as good in Italy.  I'm often in the old town these days, my main pizza options there are Kick Slice Pizza and Across 100 Pizza. Both have branches in Song Wat and Charoenkrung but despite being good Peppina is a different level.
