To get back more specifically to rdiienno’s questions:
Yes, we do reserve some our Lord’s Body and Blood, and we do have tabernacles. The way the Eucharist is reserved is that a cube is taken (the Lamb-the part that when looking at the loaf has a cross and in each quadrant made by the Cross are IC XC NI KA ). Then a little bit of the Blood is poured onto the top. This is then put into a special box for several to dry (this is important, or else the Eucharist will get moldy). This is then put into a box like the one it is dried in, but smaller, then placed in the tabernacle. This procedure happens at least once a year, on Holy Thursday, and also through out the year as needed (this is reserved for the sick).
Most tabernacles look like miniature Greek churches, and they set on the Holy Table. This is the form they are most commonly found in, but the traditional form is that of a dove suspended from the ceiling over the Holy Table (

Further-i have seen a service among Ruthenian recension Churches that resembles Benediction-though it is not this service exactly. It is called “Benediction” in English, but the Slavonic term translations literally as “Supplication”, at the end of which there is a blessing with the Eucharist as at Divine Liturgy-ie, no monstrance, the Eucharist is in a Chalice or on a Diskos ( a paten with a base) and is covered. One will these days only encounter this very rarely, mostly in Ukrainian churches.
The Temple is a special place to pray, a place where God is always present, physically, in his Body and Blood, as well as in his Word (even though the Divine Gifts may not be reserved, there is ALWAYS a Gospel Book on the Holy Table, well, almost always, the exception being at the procalmation of the Gospel). Each Temple is a meeting point between the Divine and mankind, Heaven and Earth, so it is always appropriate to keep watch with our Lord at any time, and to pray with and to Him, along with the saints. All one must do is go, be silent and know God is with us.
