Reposting from
the master thread and reiterating here as well that at the moment kosher is not so simple and the caterers and restaurants are overwhelmed and can't handle the volume. Many people are stuck without kosher as they didn't plan well.
The Armani needs week or 2 advance booking and they only have 2 seatings 630pm and 9pm
If you reserved 630, they don't give away your table until 9. Ive seen them turn away people while tables sat empty for 2 hours since people didn't show up or came late
Treat kosher is horrible food and there are many issues in terms of delivery as well
Eli's won't take orders they're too busy
There is another guy that claims to be doing food but wouldn't answer his whatsapp message so I can't comment much there
Its unorganized and many people are upset and going hungry
Sure one won't have restaurant meals if they didn't plan ahead, but there are plenty of products to not go hungry. While one can't rely on familiar products and assume they are kosher even if the logo isn't there (many companies have different factories for different markets markets), there are other options. For people not looking to cook and just looking to have basic food for a few days, kosher certified bagels and wraps can be found at Carrefour HYPERmarkets. Kosher smoked salmon like Labeyrie (only unflavored), mayonnaise (OU) or canned items like sardines (OU) are also available. Almond and soy milk, as well as dairy options from imported yogurts to cheese are available. Nestle cereals made in France (some dairy) are everywhere. In the snacking division, you can find ice cream, sorbet, KIND bars etc. all with the OU.
From what I've noticed, smaller stores like Spinney's or Carrefour markets have very small selections which can be discouraging, but one can find everything by going to one or two Carrefour hypermarket.
If one is willing/can cook, the possibilities are endless.
Here's a link to the KLBD, sadly they don't precise where each product is made, so you'd only be able to buy what is made in the UK since the company might have multiple factories:
https://www.kosher.org.uk/koshersearchThe Paris Beis Din list is a little more helpful as they add factory codes and locations when needed, although they don't include some products that KLBD does, but it's in French only:
