There syn list pretty much lists everything there is to eat even if it's too high. I think they do that more to educate those that don't really know how unhealthy some food can be.
Pizza and especially the curries can be made at home at a fraction on the syns. I'm a big lover of curries and for the same curry that a takeaway makes and adds tons of crap too I make at home syn free. There are loads of really cool slimming world recipes out there. I manage eating out by saving the high syn foods until I can make them at home and opt for pasta based dishes, chicken and other dishes that contain syn free foods. At least that way I'm not totally destroying my syn count.
If you are starting out aim for 15 syns, nothing lower just yet. If you do too much too quick you'll almost certainly give up. You're body needs time to adjust.
Most chain restaurant food like harvesters, beefeaters etc their food syn values are available online
BTW there is nothing to say you can't save syns. I do all the time and have a drink at the weekend
