Baby high chair at Local Joints?

Travelling for the first time with my 13mo toddler with much trepidation and trying our best to pack light. Wondering if we should be bringing a portable high chair to make our lives a bit easier during meals out.. in case food places don't have high chairs? but it's bulky as heck..

And how friendly are restaurants to catering to a portion of no salt no sugar for baby haha, otherwise will try to pack more on-the-go packet foods or aim to buy at akachanpo/local supermarkets? Any tips would be much appreciated.

Thank you very much!!!
