It is very nice to sit in one of the restaurants at the pond of Lyab-i Hauz Complex. It might seem to be even nicer to sit right at the bank of the pond. But beware: When the fountains are open and the water flows into the pond, it is very likely that water drops onto your table and into your beer! So: Do not sit in the first row. It is much healthier to sit in the back.
Everywhere in the old Town you can see, that the gas mains are outside of the buildings, fixed to walls a bit higher than your head. I would consider this dangerous. But on the other hand Bukhara is often hit by earthquakes, so the gas mains cannot be under the earth.
I saw this very dangerous action in the morning after arriving at Bukhara Trainstation. At least in Europe we would consider this very dangerous. But the people did not even look at it! The old woman together with the child crawled under the train with all her stuff, maybe she did not want to wait until the train leaves the station.
Do not follow their example!
The one disadvantage of the Lyab-i-Hauz is that as soon as your shashlik arrives, you will be visited by lots of large kebab-loving wasps. Fortunately they are not aggressive, and are much more interested in attacking your shashlik than in stinging you.
As I already pointed out for Khiva, Uzbeks don't place warning signs all and everywhere to prevent accidents. They trust in the common sense of their visitors.
There are no signs for example on the Ark's area to warn of the debris and stones that might cause stumbling, or on Chor Minor and other medressas or sights you can climb. No fences to protect from falling down when leaning over too much.
Well – as I wrote, it should be common sense to take care there.
Of course, high heels are the most stupid shoes to wear for visiting Bukhara, so comfortable walking shoes is a must there.
Who has read my tip on the yoghurt drink restaurant, might know it already. But I will place it as a warning here, as it seems to be most typical for Bukhara.
Bukhara's water is not safe !
Make sure, you only drink bottled water, and I would even suggest that you buy brand water, such as Nestlé.
Make sure, the bottle, you buy, is really sealed !
I am not implying something here for Bukhara or Uzbekistan, but for several countries it is known that refills into "brand" packages are done with suspicious quality products (hope, I found the correct words, non-native English speaker I am..., I know some VTers are picky with improper English hahaha).
Make sure, you don't have ice cubes somewhere in food or drinks ! The Bukharians most probably use tap water for making the cubes, and this is definitely not something to be put into our wimpy western stomachs, which are used to plastic food and overdoses of vitamins and antibiotics and have lost their abilities for self-curing !
Brushing teeth with tap water is safe enough, as long as you don't swallow it.
I really don't know, and maybe Uzbeks also don't know this, but Bukhara seems to be very "famous" for more or less serious "Montezumas". I met several people who all mentioned that they got some travellers diarrhoea there. And even in the Pamirs (= Tajikistan), when I went into a hospital, as mine simply didn't seem to vanish, the doctors smiled when I mentioned that I was in Bukhara.
So: don't let your stay in this marvellous city be spoilt by "Montezumas" and drink only bottled water and no ice cubes. And have activated carbon in your luggage !
The Islam has a wide range of hygienic rules but they can not totally prevent you from stomach upsets etc. You may expect that your digestion can run faster by orders of magnitude than at home, sometimes accompanied by fever. But you can also be lucky and not experience anything of all that. It is wise to follow all hygienic rules concerning eating in 3rd world countries (drink only tea or bottled drinks, eat only fruits you peel yourself, avoid all icecream and icecubes etc.) The shashliks are safe if they are really well cooked - avoid the small-cut marinated raw onions served with the shashlik because some marinate also the raw meat in the same dressing....
If you eat at Labi Hauz, note that on the west and north sides are restaurants. Their prices are ridiculous (especially since the food is the same as anywhere else). On the east side the cafe there is apt to charging whatever number pops into the waiter's head. You can order the same thing two days in a row and be quoted a different price both times. Invariably, these are higher than they should be. Find a local place if you're sick of this nonsense.
