My main table is this folding one from Halfords www.halfords.ie/camping-and-leisure/camping-furniture/halfords-roll-up-aluminium-table-676638.html - I throw my 1 ring gas suitcase stove on it for cooking, stand plates on their sides in the cracks to drain when washing up, it can change height and comfortably holds 4 eating (once you take off the stove!), and it folds down quite small.
I tend to just use 2 Ikea plastic storage tubs rather than a proper kitchen unit, as that's how I store them at home. 1 is the 40l box, with pots, pans, crockery, mallet, washing line, spare pegs, ....the 1,001 things you need for camping. The other is the 22l box with "housekeepers" insert - for the cooking utensils (sharp knives in individual plastic covers, wooden spoon, whisk, tin opener, corkscrew, tongs, bbq tools..), small Ikea chopping board, 100 ml travel bottle of washup liquid, washup brush, small roll bin liners, small roll tin foil, pegs, small silicon oven mitts for hot pots, bag of bamboo skewers (for BBQs, marshmallows, sharp stick to hold things together..) all sorts.
We got a good chair from Decathlon a couple of years ago - the more expensive of the 2 available but comfortable, and way less than a camping store price. I also have their lanterns (this small one for bedroom, this bigger one was my original and grand, but I got this one last year which is a good strong light (that DH has "borrowed" for the shed...he's also "borrowed" both mats I had bought (on consecutive years) for the front and back door at home....grr). Last year, I also got a solar panel (Decathlon's 3 panel one) and decent sized powerbank to charge from it - not cheap but worth it! I like the lanterns that can be recharged from either (one of mine needs batteries, the other 2 are rechargeable).
I use Ikea kids plastic plates as they have a lip on them and were nice and cheap. A lot of my stuff is Ikea and Decathlon rather than camping store items, but work well. Lidl and Aldi's "middle aisle" camping and outdoor gear can be good too - I have a nice small BBQ and a few other bits from there. And lots of Ikea/Primark fleeces as rugs, and Ikea blue bags to cart things there in (a fellow Cub Scout Leader gives 1 each to his DCs as their "wardrobe" when camping as they can tidy easily, rummage and find clean things much easier when needed than the dark depths of a gear bag/rucksack and each knows which is their bag at the end of their sleeping space - but then all can be easily squashed back into the car at the end).
